I'm an associate professor in the Department of Fish and Wildlife Resources in the College of Natural Resources at the University of Idaho. I joined the department in 2007 after six years on the faculty at Southern Illinois University. I earned undergraduate and master degrees from Trent University in Peterborough, Ontario, followed by a doctorate degree from the University of Alberta in Edmonton, Alberta. I am a limnologist with relatively broad interests. My Ph.D. and post-doc research made use of natural temperature gradients to examine the life history and reproductive strategies of invertebrates with the goal to predict population level responses to large-scale climatic change. More recently, I have examined the effectiveness of various restoration methods on aquatic ecosystems; this portion of my research is continuing in Idaho.

"Determining the role of Mysis relicta in the cycling of nutrients in the pelagic zone of Lake Pend Oreille" Bayview, Idaho, USA, Jan. 2009 - March 2012
The goals of this research are to quantify the role that the introduced species, Mysis relicta
– a small crustacean shrimp – plays in the vertical transport of nutrients in the Lake Pend Oreille ecosystem. Because of the lake's great depth (>350 m), shrimp migrating to the surface should have empty guts and thus not contribute to nutrient regeneration while in surface waters. Night time feeding at the surface with subsequent downward migration at dawn represents the net export of material from surface waters. This material then is unavailable for the production in surface waters. Our goal is quantify the nutrients exported via mysids."Investigating the mechanism by which long-distance circulation reduces or mitigates harmful algal blooms in lakes and reservoirs" Heppner, Oregon, USA, June 2008 - Dec. 2011
The goal of this research is to understand the mechanism(s) by which long distance circulators prevent or mitigate harmful algal blooms in lakes and reservoirs. With an increasing world population, but limited amounts of freshwaters, we must safeguard and restore, where possible, the water available to us. Our land use activities increase the transport of nutrients into receiving water bodies, often resulting in unbalanced conditions that provide ideal conditions algae that from unsightly and often dangerous blooms. Under certain conditions, species are favored that produce the most potent toxins known to humans, which is of special concern in reservoirs and lakes which serve as drinking water supplies or recreational purposes. A company has designed a solar-powered machine to circulate water that mitigates or prevents such blooms, but the mechanism(s) by which it works are not fully understood. Our research aims to address this knowledge gap. "Establishing a laboratory rearing protocol for the endangered Illinois cave amphipod to aid its recovery" Waterloo, Illinois, USA, July 2007 - Dec. 2012
The goal of this research are to determine the conditions under which this endangered species can be kept and propagated in the laboratory. Ultimately this will allow researchers to establish an artificial population to procure individuals for use in stress tests to determine which environmental parameters and concentrations are lethal to it. This will allow managers to provide defensible minimum water quality criteria for areas where the amphipod occurs to aid its long-term survival and ultimately its recovery from endangered status.
